Why am I constantly supplying Firefox as a parameter? Well, the answer is that those functions *need* a browser to use, they can't get away with getting it from somewhere else. There is no somewhere else, as there is no POSIX standard way of letting a user define a preferred browser (yes, I know about Debian's x-www-browser stuff, but that's Debian, and I know about environmental variables, but I don't think there's any standard $BROWSER like there is $HOME or $EDITOR).
Why not just use BROWSER even though it isn't commonly defined? Just define a getBrowser = getEnv "BROWSER" `catch` \_ -> return "firefox" and it's still just one line (well, plus an import) to define a default browser in xmonad.hs by calling setEnv in the startupHook (or in main before calling xmonad). And lo, users are now also able to define their browser preferences in a non-xmonad-specific location! I don't like the idea of cluttering up XConfig with this sort of thing. I'd rather see the terminal pref removed (it seems silly for all the same reasons) than another pref (that's only used in contrib) added to the core of xmonad. If you prefer, we could alternately support XMONAD_BROWSER. Note that putting the browser in the environment would also make it immediately runtime-configurable (well, with a few lines of code in contrib). -- David Roundy Department of Physics Oregon State University
